Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	In July 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-07, "Codification Updates to SEC Sections". ASU No. 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC's regulations, thereby eliminating redundancies. This ASU is effective upon issuance and did not have a significant impact on the Company's consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)". The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The FASB subsequently issued ASU No. 2018-19, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses", in November 2018 which provided further guidance on assessment of receivables for operating leases. ASU No. 2019-04, "Codification Improvements to Topic 326, Topic 815 and Topic 825" and ASU No. 2019-05, "Targeted Transition Relief", that were issued in April and May of 2019 do not materially impact the Company. The Company anticipates ASU 2016-13 and ASU 2018-19 will apply to its trade receivables and will not have a material impact on the reported value of such receivables. We expect to implement ASU No. 2016-13 and 2018-19 on the effective date of January 1, 2020. Accounting Pronouncements Implemented in the Nine Months Ended September 30, 2019 In June 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting". The ASU changed the measurement date for determining the fair value of share awards to nonemployees to the grant date and requires the consideration of the probability of satisfying performance obligations in assessing the awards. The ASU did not have a material impact on our recognition of share-based payments for nonemployees.
Leases	Lease Accounting In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" followed by ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", issued in July 2018. The ASU is intended to increase transparency and comparability among companies by recognizing lease assets and liabilities and disclosing key information about leasing arrangements. ASU 2016-02 was adopted by the Company on January 1, 2019. In accordance with Topic 842, we elected not to recognize lease assets and lease liabilities for leases with a term of twelve months or less and elected to not separate lease and non-lease components. We elected the transition method option under ASU 2018-11 with the package of practical expedients that permits the Company to: (a) not reassess whether expired or existing contracts contain leases, (b) not reassess lease classification for existing or expired leases and (c) not consider whether previously capitalized initial direct costs would be appropriate under the new standard. We recorded a right-of-use asset of $21.2 million and a lease liability of $22.2 million upon adoption. We also elected the option to apply the new leasing standard on the date of adoption and recognize a cumulative-effect transition adjustment to the opening balance of retained earnings in the period of adoption resulting in a cumulative effect as of January 1, 2019 of $0.1 million As disclosed in footnote 12, we lease office, warehouse and manufacturing space and certain equipment under non-cancelable operating lease agreements that generally require us to pay maintenance, insurance, taxes and other expenses in addition to annual rental fees. As of September 30, 2019, our equipment leases did not provide for any material guarantee of a specified portion of residual values.
Revenue Recognition	Contractual Arrangements Revenue is measured based on terms and considerations specified in contracts with customers. We have long-term contracts with some customers that govern overall terms and conditions accompanied by individual purchase orders that define specific order quantities and/or price. We have many customers that operate under terms outlined in purchase orders without a long-term contract. We generally do not have customer contracts with minimum order quantity requirements. Amount and Timing of Revenue Recognition The transaction price is based on the consideration to which the Company will be entitled in exchange for transferring control of a product to the customer. This is defined in a purchase order or in a separate pricing arrangement and represents the stand-alone selling price. Our payment terms vary by the type and location of our customer and the products offered. None of the Company's contracts as of September 30, 2019 contained a significant financing component. We typically do not have multiple performance obligations requiring us to allocate a transaction price. We recognize revenue at the point in time when we satisfy a performance obligation by transferring control of a product to a customer, usually at a designated shipping point and in accordance with customer specifications. We make estimates for potential customer returns or adjustments based on historical experience, which reduce revenues. Other Matters Shipping and handling costs billed to customers are recorded in revenues and costs associated with outbound freight are generally accounted for as a fulfillment cost and are included in cost of revenues. We generally do not provide for extended warranties or material customer incentives. Our customers typically do not have a general right of return for our products. We had outstanding customer accounts receivable, net of allowances, of $153.2 million as of September 30, 2019 and $134.6 million as of December 31, 2018. We generally do not have other assets or liabilities associated with customer contracts. In general, we do not make significant judgments or have variable consideration that impact our recognition of revenue. Our products include electrical wire harnesses and panel assemblies; trim systems and components ("Trim"); cab structures and sleeper boxes; mirrors, wipers and controls; and seats and seating systems ("Seats"). We sell these products into multiple geographic regions including North America, Europe and Asia-Pacific and to multiple customer end markets including MD/HD Truck OEMs, Bus OEMs, Construction OEMs, the aftermarket and other markets. The nature, timing and uncertainty of our recognition of revenue and associated cash flows across the varying product lines, geographic regions and customer end markets are substantially consistent. Refer to footnote 16 for revenue disclosures by reportable segments.
Accounts Receivable	Trade accounts receivable are stated at current value less allowances, which approximates fair value. We review our receivables on an ongoing basis to ensure that they are properly valued and collectible. We record estimates of returns or allowances resulting from quality, delivery, discounts or other issues affecting the value of receivables. This amount is estimated based on historical trends and current market conditions, with the offset to revenues. The allowance for doubtful accounts is used to record the estimated risk of loss related to our customers’ inability to pay. This allowance is maintained at a level that we consider appropriate based on factors that affect collectability, such as the financial health of our customers, historical trends of charge-offs and recoveries and current economic market conditions. As we monitor our receivables, we identify customers that may have payment problems, and we adjust the allowance accordingly, with the offset to selling, general and administrative expense. Account balances are charged off against the allowance when recovery is considered remote.
Warranty	We are subject to warranty claims for products that fail to perform as expected due to design or manufacturing deficiencies. Customers generally require their outside suppliers to guarantee or warrant their products and bear the cost of repair or replacement of such products. Depending on the terms under which we supply products to our customers, a customer may hold us responsible for some or all of the repair or replacement costs of defective products when the product supplied did not perform as represented. Our policy is to reserve for estimated future customer warranty costs based on historical trends and current economic factors.
